This article mainly introduces the database to achieve database security control technology, the article is very detailed, has a certain reference value, interested friends must read it!

The security of the database refers to protecting the database from data leakage, change or destruction caused by illegal use. The technology to realize database security control: 1, user identification and authentication; 2, access control; 3, view mechanism; 4, audit; 5, data encryption.

The operating environment of this tutorial: windows7 system, mysql8 version, Dell G3 computer.

The security of the database refers to protecting the database from data leakage, change or destruction caused by illegal use.

Security issues are not unique to database systems, but are common to all computer systems. Only a large amount of data is centrally stored in the database system, and it is directly shared by many end users, which makes the security problem more prominent. Whether the system security measures are effective or not is one of the main indicators of the database system. The security of database and computer system, including the security of operating system and network system, are closely related and supported each other.

The common methods and techniques to realize database security control are:

(1) user identification and authentication: this method provides a certain way for users to identify their own name or identity. Every time the user requests to enter the system, it will be checked by the system, and the right to use the system will be provided after passing the appraisal.

(2) access control: through the definition of user rights and legal rights check to ensure that only legally authorized users access the database, all unauthorized personnel cannot access data. For example, discretionary access control (I) AC in level C2 and mandatory access control (M.AC) in level Bl.

(3) View mechanism: define views for different users, and hide the data to be kept secret from the users who have no right to access through the view mechanism, so as to automatically provide a certain degree of security protection to the data.

(4) Audit: establish an audit log, and automatically record all the operations of the user to the database and put it in the audit log. DBA can use the information tracked by the audit to reproduce a series of events that lead to the current situation of the database, and find out the person, time and content of illegally accessing the data.

(5) data encryption: encrypts the stored and transmitted data so that people who do not know the decryption algorithm cannot know the contents of the data.
